[Surgical management of post-caustic prepyloric stenosis. The Y-V intravascular segmental antrectomy (considerations on 71 cases)].

The author presents 71 cases of gastric stenoses following caustic lesions, of which 20 were located in the stomach and 51 also involved the oesophagus (oesophagian stenosis). In cases with limited antrum stenoses the author performed antrectomy and gastro-duodenal anastomosis. In the pre-pylorus stenoses, when these were located at 3--5 cm from the pylorus the author recommends the conservation of the denevated pylorus by double pylorotomy and anastomosis with the entire gastric section. He describes a personal procedure which he calls: The Y--V intravascular segmental antrectomy". In cases with extensive gastric stenoses (over 75% of the area), as well as in evolutive corrosion lesions the author recommends Y-jejunostomy, of the Maydl type.
